  This hook loads the necessary modules for a network device.
  Detection will take place at runtime. To minimize the modules
  in the image, add the autodetect hook too.
  For pcmcia net devices please use pcmcia hook too.

  Kernel Parameters:
  An interface spec can be either short form, which is just the name of
  an interface (eth0 or whatever), or long form.  The long form consists
  of up to seven elements, separated by colons:

  ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
  nfsaddrs= is an alias to ip= and can be used too.

  <client-ip>	IP address of the client. If empty, the address will
                either be determined by RARP/BOOTP/DHCP. What protocol
                is used de- pends on the <autoconf> parameter. If this
                parameter is not empty, autoconf will be used.

  <server-ip>   IP address of the NFS server. If RARP is used to
                determine the client address and this parameter is NOT
                empty only replies from the specified server are
                accepted. To use different RARP and NFS server,
                specify your RARP server here (or leave it blank), and
                specify your NFS server in the 'nfsroot' parameter
                (see above). If this entry is blank the address of the
                server is used which answered the RARP/BOOTP/DHCP
                request.

  <gw-ip>       IP address of a gateway if the server is on a different
                subnet. If this entry is empty no gateway is used and the
                server is assumed to be on the local network, unless a
                value has been received by BOOTP/DHCP.

  <netmask>     Netmask for local network interface. If this is empty,
                the netmask is derived from the client IP address assuming
                classful addressing, unless overridden in BOOTP/DHCP reply.

  <hostname>    Name of the client. If empty, the client IP address is
                used in ASCII notation, or the value received by
                BOOTP/DHCP.

  <device>      Name of network device to use. If this is empty, all
                devices are used for RARP/BOOTP/DHCP requests, and the
                first one we receive a reply on is configured. If you
                have only one device, you can safely leave this blank.

  <autoconf>	Method to use for autoconfiguration. If this is either
                'rarp', 'bootp', or 'dhcp' the specified protocol is
                used.  If the value is 'both', 'all' or empty, all
                protocols are used.  'off', 'static' or 'none' means
                no autoconfiguration.
  Examples:
  ip=127.0.0.1:::::lo:none  --> Enable the loopback interface.
  ip=192.168.1.1:::::eth2:none --> Enable static eth2 interface.
  ip=:::::eth0:dhcp --> Enable dhcp protcol for eth0 configuration.

  nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]

  If the 'nfsroot' parameter is NOT given on the command line, the default
  "/tftpboot/%s" will be used.

  <server-ip>   Specifies the IP address of the NFS server. If this field
                is not given, the default address as determined by the
                'ip' variable (see below) is used. One use of this
                parameter is for example to allow using different servers
                for RARP and NFS. Usually you can leave this blank.

  <root-dir>    Name of the directory on the server to mount as root. If
                there is a "%s" token in the string, the token will be
                replaced by the ASCII-representation of the client's IP
                address.

  <nfs-options> Standard NFS options. All options are separated by commas.
                If the options field is not given, the following defaults
                will be used:
                        port            = as given by server portmap daemon
                        rsize           = 1024
                        wsize           = 1024
                        timeo           = 7
                        retrans         = 3
                        acregmin        = 3
                        acregmax        = 60
                        acdirmin        = 30
                        acdirmax        = 60
                        flags           = hard, nointr, noposix, cto, ac

  root=/dev/nfs

  If you don't use nfsroot= parameter you need to set root=/dev/nfs
  to boot from a nfs root by autoconfiguration.
